This was the perfect shower system for our bathroom remodel.  Love the Spotshield Brushed Nickel finish with our wall tile!  We ended up with two 
rough in boxes instead of one rough in and one trim box as well as missing cartridges which held up our project a bit.  Contacted Customer Service and was put in contact with manufacturer, with whom I was unable to resolve the issue of missing parts.  Went back to Wayfair and requested a replacement item.  When I double-checked with Customer Service, I reached a very helpful rep who actually placed the replacement order.  Rec'd the replacement with all the right parts, plumber finished the installation, boxed up the leftovers and I contacted Wayfair for a return label and sent it back.  Wayfair confirmed the issue resolved.  Very satisfied with product and final resoluton of order.
